Quality Common Scoring

Providing feedback on inspections

Applied to all Key Stage and Risk Based Inspections, this is the same scoring we use for Pride in the Job and Construction Quality Reviews. Scores are 1-6 where 4 indicates compliance with NHBC Standards, 1 is very poor and 6 is outstanding work.

Managing Directors and Construction Directors can now access the Quality Common Scoring (QCS) data for the sites across their business via the My NHBC Portal. This data provides a new level of insight and visibility of quality across sites or by region. The scoring data will show, by key stage, which inspections are compliant (right first time), which are good quality (beyond compliance) and which are poor quality (of concern and need addressing), helping to manage consistency and identify areas of focus.

Reportable Items

If Reportable Items are found during an inspection, a score of 1, 2 or 3 is automatically recorded based on the cumulative total of the Damage Potential Rating of each Reportable Item in that inspection. If no Reportable Items are found, a score of at least 4 will be given with a 5 or 6 being possible for very good or outstanding quality of work.

Damage potential rating

Damage potential rating is a pre-determined weighting applied to each Reportable Item depending on the severity of the item. It is based on claims potential, health and safety, Building Regulations and homeowner disruption.

Recording scores

NHBC Building Inspectors record the score for each Key Stage Inspection on the matrix page in the Site Record Book and discuss scores with the site manager at the end of each visit.

Example scoring data

The chart below shows how the range of scores can be reviewed for each of the key stage inspections of houses using the raw data made available to you.

The shades of blue and green represent compliant inspections (e.g. Pre-handovers are below 70% compliance)

The shades of green represent quality that exceeds compliance

The shades of red represent poor quality, where multiple or serious issues were identified.

Reviewing the data in this way helps to build a picture of the areas of strength and weakness.
